DETAILED DESCRIPTION

FIG. 1 illustrates a workplace risk factor identification system 100 for enabling a process for automatically performing a multi-scale spatiotemporal analytics process for monitoring, visualization, prediction, and prescriptive management of workplace safety risks, in accordance with embodiments of the present invention. System 100 comprises components enabling a process that includes active monitoring and recording of: workplace injury events, a type of injury, a demographic profile of individuals involved with the injury, and associated productivity loss/costs. System 100 additionally predicts future injury events/risks including, inter alia, a timing of an injury, an injury type, a work location, propensity scores, and associated demographics using a multi-scale spatiotemporal analytical model that combines multiple time series and clustering models each generated in a different scale in space and time. System 100 uses the predicted risks to prescribe an investment budget for mitigating predicted injury risks via usage of a cost of injury model. System 100 additionally enables an end user 114 to manage workplace risks via an interactive spatio-temporal visualization engine feeding directly into an associated mobile device.

System 100 of FIG. 1 includes data warehouse system 102 connected through a network 7 to an analytical computing system 104 and a user interface system 108. Additionally, data warehouse system 102 may comprise (internally) or be connected to a monitor system 109 comprising multiple differing sensors. Each of data warehouse system 102, analytical computing system 104, monitor system 109, and user interface system 108 may comprise or be comprised by an embedded controller. An embedded controller is defined herein as a computer comprising a dedicated functionality that enables various system tasks that an operating system does not handle. An embedded controller may include specific internal dedicated hardware such as a microcontroller (a CPU comprising integrated memory and peripherals), internal integrated sensors, (i.e., dedicated monitoring hardware), and internal integrated GPS hardware. Additionally, an embedded controller may include its own RAM and flash ROM for its own internal software. Each of data warehouse system 102, analytical computing system 104, monitor system, and user interface system 108 may include a CPU, dedicated monitoring hardware, and a memory system. The memory system 8 may include a single memory system. Alternatively, the memory system may include a plurality of memory systems. Network 7 may include any type of network including, inter alia, a local area network, (LAN), a wide area network (WAN), the Internet, a wireless network, etc.

Monitor system 109 comprises sensors for monitoring workplace injury events. The workplace injury events may be monitored via a plurality of sensing devices including, inter alia, RFID sensors for identification, video camera based sensors for automatically recording the workplace injury events (for performing a root cause analysis), and mobile device type sensors for near real time reporting of the injury events. All monitored or reported workplace injury events are stored in a data warehouse 102 (e.g., a centralized server) for further analysis with respect to tagging events that resulted in loss time. Workplace injury events may include, inter alia, body stressing related injuries, traffic accident related injuries, hitting objects with a part of the body related injuries, illness/medical condition related injuries, biological factor related injuries, mental stress related injuries, fall related injuries, ergonomic related injuries, chemical related injuries, heat related injuries, etc. The workplace injury events may be associated or correlated with employee demographics, a location of a workplace, activities at a workplace, etc. Data ware house 102 stores all data related to time and type of incident, demographics of the employee, loss time, SME review report of the incident, etc.

Analytical computing system 104 comprises an analytical engine 107 comprising a predictive engine module 107 a and a prescriptive engine module 107 b. Predictive engine module 107 a enables a process for predicting future workplace injury events by analyzing historic injury event data stored in data warehouse 102. The historic injury event data is ingested by a centralized processing unit (of analytical computing system 104) and predictive engine module 107 a is executed to create a prediction with respect to an occurrence of future workplace injury events. The predicted future workplace injury events are sorted based on: a time of occurrence, a location and frequency of an occurrence, demographics of the employee with respect to being prone to workplace injury events, and a severity of workplace injury events. Prescriptive engine module 107 b is enabled to prescribe injury risk mitigation actions. The predicted and sorted future workplace injury events (i.e., generated and sorted by predictive engine module 107 a) comprise an input to prescriptive engine module 107 b. Prescriptive engine module 107 b generates as an output: incident risk resolution options, a cost of resolution option, and an expected gain in terms of cost savings from a reduced incident rate. In response, a workplace supervisor may navigate (via user interface system 108 and/or a mobile device) existing risk resolution steps requiring attention. Additionally, workplace supervisor may prioritize existing risk resolution steps comprising a highest impact. Additionally, system 100 comprises an optimization system for generating a cost optimized risk resolution plan based on a predicted incidents frequency and a severity and the cost of a resolution.

User interface system 108 comprises a graphical user interface (GUI) that displays all resulting output from predictive engine module 107 a and prescriptive engine module 107 b.

FIG. 2 illustrates a block diagram detailing a process flow enabled by predictive engine module 107 a of FIG. 1 for predicting future workplace injury events, in accordance with embodiments of the present invention. The process flow detailed with respect to FIG. 2 retrieves historical injury event data 202 recorded in a centralized system. In response, a centralized processing unit ingests historic injury event data 202 to generate a prediction with respect to an occurrence of future injury events by: a time of occurrence, a location and frequency of occurrence, and demographics with respect to an employee likely to be prone to the future injury events. The following block sequence of steps illustrates the process for predicting future workplace injury events:

Block 202 represents historical injury event data 202 recorded in a centralized system. Historical injury event data 202 comprises enterprise HR data and incident records data.

Block 207 enables a process for using historical incident data to identify various incident types and predict an occurrence rate for the a next specified month period by enabling a text analytics process with respect to incident text for extraction of keywords describing an incident.

Block 209 performs a hierarchical clustering process with respect to incident keywords (via usage of Ward's method) to obtain a set of distinct incident types defined by incident description text. Block 211 executes a set of time series models for each incident cluster type to predict a rate of future occurrence for each incident type.

Block 214 uses historic enterprise HR data to evaluate worked man hours for each employee by month and year. Time series models are enabled to predict productive man hours per a next specified month period. Additionally, the historic enterprise HR data and incident data are used to extract a demographic pattern of occurrence for various incident types. A random forest model is used (in block 218) to extract important demographic features followed by an aggregation and isolation process with respect to a frequency of occurrence of each incident type for a selected feature vector.

Block 220 executes a clustering algorithm to cluster demographic attributes by occurrence of frequencies across all identified incident types. Block 224 extracts demographic profiles of an active population and predicts a cluster id for an associated demographic profile. Block 228 normalizes a cluster level prediction by evaluating a proportional contribution of a demographic feature vector with respect to each incident type. Additionally, all models are combined to predict an incident type, a rate, and a detailed analytical model with respect to employee demographic features.

FIG. 3 illustrates a block diagram detailing a process flow enabled by prescriptive engine module 107 b of FIG. 1 for prescribing injury risk mitigation actions related to workplace injury events, in accordance with embodiments of the present invention. The following block sequence of steps illustrates the process for prescribing injury risk mitigation actions related to workplace injury events:

Block 310 retrieves predicted output data 302 (from predictive engine module 107 a of FIG. 1) and active employee related data 304 and illustrates employees at two differing locations with respect to an indication related to what type of workplace injury events are more likely to occur at the two differing locations.

Block 312 computes a productivity loss and additional injury claims costs expected to be incurred by an organization due to predicted future workplace injury events for each type.

Block 308 represents a business strategy and operations data input outlining: a set of actions for reducing injury risks, a cost to an organization for each action, and business targets for productivity and injury rates.

Block 314 represents an optimization model for computing an optimal action for mitigating an injury risk by generating recommended actions for correcting root causes for workplace injury events resulting in a maximal gain in productivity at a minimal cost of action. In response, a workplace supervisor may act on the recommended actions a user interface.

Block 318 represents an injury management decision unit for managing executed actions with respect to business constraints and budget issues.

Block 320 represents an engine for computing an adjusted risk with respect to an executed action for eliminating a cause of an injury.

Block 324 computes a realized return on investment for a selected action the realized return is computed with respect to reduced injury rates due to executing a risk mitigation action. Additionally, the optimization model (of block 314) continues to re-evaluate a next best action using realized returns data, past executed actions, predicted injury risks by region, business targets, and a leftover allocated budget.

An LTIFR value 521 may be presented in another color to illustrate a post AC repair action causing stress related injuries at the location.

FIG. 6 illustrates an algorithm detailing a process flow enabled by system 100 of FIG. 1 for automatically performing a multi-scale spatiotemporal analytics process for monitoring, visualization, prediction, and prescriptive management of workplace safety risks, in accordance with embodiments of the present invention. Each of the steps in the algorithm of FIG. 6 may be enabled and executed in any order by a computer processor executing computer code. In step 600, a plurality of workplace injury based events (associated with a plurality of individuals at a multisite distributed workplace environment) are monitored by a centralized server via execution of multiple geographically distributed sensor devices. The plurality of workplace injury based events may include, inter alia, body stress events, motor vehicle accident related events, bodily injury related events, medical condition related events, biological factor related events, mental stress related events, chemical accident related events, heat related events, etc. In step 602, current injury data describing the plurality of workplace injury based events is stored. In step 604, predicted future workplace injury based events (associated with future workplace injury based events with respect to a predicted plurality of individuals at the multisite distributed workplace environment) are generating based on the current injury data and previously retrieved injury data describing previously retrieved historical workplace injury based events. The predicted future workplace injury based events may be generated with respect to future times of occurrence, future locations and frequencies of occurrence, and demographics with respect to the predicted plurality of individuals at the multisite distributed workplace environment. Generating the predicted future workplace injury based events may include:

1. Identifying event types associated with the predicted future workplace injury based events.

2. Predicting hours worked by the individuals with respect to a month and a year.

3. Extracting (from the current injury data and previously retrieved injury data) a demographics pattern with respect to occurrences of the event types.

Identifying the event type may include:

1. Executing a text analytics process and a hierarchal clustering process with respect to the current injury data to identify distinct injury type signatures.

2. Evaluating a probabilistic map with respect to an injury signature of the injury type signatures that is associated with the demographics pattern via a series of classification processes.

3. Computing a severity or loss time impact of each injury signature of the distinct injury type signatures.

4. Identifying a root cause with respect to each injury signature via a text analytics process applied to an injury log.

5. Reviewing information associated with the root cause.

6. Executing a set of time series models to predict an incident rate with respect to the injury type signatures.

Extracting the demographics pattern may include:

1. Executing a random forest model with respect to extracting important demographic features of the individuals.

2. Isolating a frequency of occurrence with respect to each event type based on a selected feature vector.

3. Executing a clustering algorithm to cluster the predicted future workplace injury based events based on a frequency of occurrence across the event types.

In step 608, injury risk mitigating actions associated with prevention of the predicted future workplace injury based events are generated based on the predicted future workplace injury based events. In step 610, a cost optimized reduction plan for prioritized implementation of the injury risk mitigating actions is generated based the injury risk mitigating actions. A process for generating the injury risk mitigation actions may include executing a integer linear program to extract a prioritized list of risk mitigation actions from a list comprising the distinct injury type signatures. Executing the integer linear program may be based on: a predicted frequency, severity, and expected loss per event of each injury signature; an estimated cost of injury risk mitigation steps for each injury signature; and a process for maximizing a return on investment for each injury signature. In step 612, the injury risk mitigating actions and the cost optimized reduction plan are transmitted to a mobile device executing an interactive spatio-temporal application for presentation to a user.
